Checking the underhood space
Places to check for possible oil leaks: 1 - oil level indicator (dipstick) in the engine crankcase; 2 - crankcase ventilation hose; 3 - cylinder head; 4 - head cover; 5 - small branch crankcase ventilation hose; 6 - large branch crankcase ventilation hose; 7 - gearbox oil level indicator (dipstick)
Recommendations:
- Check the seals regularly, especially on a new car, to detect hidden defects.
- If you find traces of fluid leakage, first wipe the area thoroughly and inspect it after some time. The appearance of new traces of leakage indicates the presence of a leak. To eliminate it, contact specialists.
- Oil leakage from several places in the engine at the same time can be caused by pinched crankcase ventilation hoses.
